The Chorda A- and D-strings are of plain sheep gut. The G- and C-strings are wound with a silver-plated copper wire and are unpolished. A brilliant and soft sound with enormous possibilities. Very low string tension, comfortable left hand feeling. Designed for 440 Hz tuning. For 415 Hz tuning, please use gauge "strong". Altering the PM gauge by 1/2 PM changes the tension by 4%. Authentic strings for baroque instruments.
